Seeking advice on creating a function in Javascript to determine if a string contains only UTF8 characters. The goal is to return true if the string has no non-UTF8 characters, and false if it does. No character replacement is needed, just a validation check to inform the user via a pop-up window or other form of validation. Any help would be appreciated, thank you!
Strings in JavaScript are made up of Unicode characters, all of which can be encoded in UTF-8. This means that any string in JavaScript is incapable of including any "non-UTF8 characters".
